SkullKnightmon is an Unknown Level Digimon that resembles a dark knight that wields two red spears and has glowing red eyes on his chest. His brother is Axemon.
He first appeared when AxeKnightmon split himself to become SkullKnightmon and Axemon to fight Shoutmon X4 and MetalGreymon. Then SkullKnightmon became SkullKnightmon Bigaxe Mode to finish off Shoutmon X4 and MetalGreymon.
